Are precious metals magnetic?

Some forms of steel are magnetic, while others are not. Non-magnetic metals include aluminum, copper, lead, tin, titanium and zinc, and alloys such as brass and bronze.

precious metals

such as gold and silver are not magnetic. Gold, silver and platinum are not magnetic.

The next time you see a precious metal, put it to the test. Take your coin or piece of jewelry and place a strong magnet on top of the object. Slowly tilt the metal object to see if the magnet sticks to the object by the magnetic pull or if it slides to the ground. In other words, precious metals are not magnetic metals, and if they show any magnetic properties, it often means that the metal you are viewing is fake, for example, a plated metal or perhaps a precious metal alloyed with a large percentage of a magnetic metal.

As a result, the magnet test is often used to check the purity or fineness of precious metals, especially gold, silver and platinum. That said, the latter is often alloyed with metals such as palladium, ruthenium, and cobalt, but only when platinum is alloyed with large amounts of cobalt will it appear to have magnetic properties. By itself, gold is not attracted to the magnetic fields we encounter in our daily lives. If you have a massive magnetic field, gold will be slightly magnetic.

It's safe to say that, for practical purposes, gold is not magnetic. These include precious metals such as gold, silver, platinum, titanium, tungsten, and palladium. However, other non-magnetic materials include stainless steel, copper, aluminum, pewter, zinc, and non-metals such as plastic. Silver is not magnetic, even with the strongest magnet.

If you hold a silver coin at 45 degrees, a suitable magnet will slowly slide down. This is because the moving magnet establishes an “electric field” * that slows its fall. Now try it with a non-magnetic coin (most coins), the magnet, as expected, simply “falls” out of the coin. This is not a warranty test for silver.

Copper is also diamagnetic (although not as strong as silver). Most silver-plated items are made of silver on copper. Therefore, if a magnet “sticks” to the item, it cannot be silver or copper. If a suitable magnet shows the diamagnetic effect, the item could be silver (most likely with a coin) or it could be plated with silver on copper.

The QUICKTEST “magnet tester” for silver. We supply three magnets suitable for you to test coins of any size, I say the magnets are “right” because if a magnet is too heavy it won't work and if it's too weak it won't work. We have chosen three small but very powerful magnets (neodymium). You will receive all three magnets, a copper coin** (98% copper) to test, a carrying bag and instructions.

An ingot bar) is not magnetic. The jewelry is made of a mixture (alloy) of gold and other metals. Varying the percentage (expressed as “carats”) of copper and silver results in yellow, red, or pink gold; none of these are magnetic. White gold will contain silver, and maybe palladium (none magnetic) or nickel (which is magnetic, but the proportion of nickel will be very low).

So no matter what the mix of gold (carats) is, you won't be able to detect gold with a magnet. WHITE GOLDIf you have read all of the above very carefully, you may have noticed that white gold may contain a small percentage of nickel and platinum may contain a small percentage of cobalt, and both are magnetic. A magnet won't attract white gold, but it will (if it's strong enough) attract platinum. This is because cobalt is three times more magnetic than nickel.

There are only a few metals that we encounter daily that are magnetic, including ferritic metals such as iron, nickel and cobalt. Other less commonly found magnetic metals include samarium, neodymium, and gadolinium. So, that means there are many metals that may look like silver but aren't magnetic, such as aluminum, zinc, and pewter. As you know, zinc, a non-magnetic metal, constitutes only a thin layer in steel centers, and steel contains ferromagnetic metallic iron.

There may even be other metals such as copper, platinum or nickel mixed with gold to give it different colors. If you have any questions about your gold or silver items, consider consulting a precious metal refinery such as Manhattan Gold and Silver. When you think of precious metals, you probably think of expensive jewelry, Tiffany's cases, or the intricate gears of an expensive watch. This, in and of itself, does not mean that the metal is platinum (many white metals are magnetic), but it does mean that you should perform further testing and not automatically discard it.

Precious metals are essentially non-magnetic, so one of the most reliable tests for real gold or silver is magnetic testing, in which materials containing silver or gold show no sign of magnet attraction or repulsion. Gold is not a magnetic metal, and pure gold in the form of coins or ingots will have no magnetic properties at all. But because these materials are valuable, counterfeiters and jewelers also use mixed metals or other substances to counterfeit the appearance of gold, silver, platinum, or palladium. Purity marks indicate the indicated purity (or percentage) of the specific type of metal used in the production of the jewelry.

Although silver and gold are not magnetic, this does not mean that non-magnetic objects are always real precious metals. Note that, in addition to iron, other metals with magnetic properties include cobalt and nickel, among other alloys. Always buy precious metal items from a reputable seller; it's usually not a good idea to buy something valuable from just anyone. .
